DEVICE FOR UTILIZING ENGlNE-EXHAUST FOR HEATING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 670,080, dated March 19, 1901. Application filed March 23,1900. Serial No. 9,901. @To modal.)

To @ZZ whom t may concer-n.-

Be it known that I, ELEAZER KEMPSHALL, a citizen ofthe United Statesp'esiding at Newton, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Devices for UtilizingT Engine-Exhaust for Heating Purposes, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in engines for use in motor-carriages, and has especial reference to that class of such engines which are internally explosive.

The object of my invention is to utilize the exhaust gas or steam, as the case may be, to heat a foot-warmer or other form of heater located at such place as may be convenient and serviceable to thc rider.

My invention will now be fully and clearly described, having reference to `the accompanying drawings, and the novel features thereof will be particularly pointed out in the claim at the close of this specication.

The drawings representin Figure 1 thereol` a plan of one form of engine embodying my invention. The form of engine shown is an internally-explosive double-cylinder gasolene-engine, but vmy invention is equally applicable to engines in which steam is em ployed as the motive force and also to engines in which only one cylinder is used. Fig. 2 is a partly-sectional View showinga form of muffler which may be employed in carrying my invention into effect.

1 represents the crank 2 3, the pistonrods; 4, one of the pistons, and 5 6 the two cylinders. 7 Sare the two exhanstpipes,lead

ing, respectively, from said cylinders and are connected with the ordinary eXhaust-cyiinder' or muiiier 9 by the pipes 10 11. Said pipes 10 11 are provided, respectively, with valves 12 13, by which the passage to the said mufiier 9 may be closed.

A secondary exhaust-cylinder or muiiier 14 is connected with exhaust-pipe 7, which leads from cylinder 5, by pipe 15 and with exhaustpipe 8,which leads from the other cylinder 6,

Athe openings 23 in the successive by pipe 16.. Pipes15 16 are respectively pro- .vided with valves 17 18, which control the admission of exhaust gases or steam into the mufer 11. This secondary exhaust-cylinder or muier 14 may be adapted as a foot-warmer and placed in any suitable location and. beof any suitable form for the purpose, or it may be of any form and placed in any location in the Wagon to serve a heat-radiator.

When it is desired to utilize the heatermni'iier, the valves 12 13,1eading` to the muffler 9, are closed and the valves 17 18am opened. When it is not desired to warm the heater, the valves 17 1S are closed and the valves 12 13 are opened. The-object of having the two sets of muiiers is to have the ordinary muier 9l located in such position removed from the person of the rider that he will not be inconvenienced by the heat when he is sniriciently warm without it.

The cylinders 9 and 14 are each preferably divided midway of their length, so that each in reality contains two inufliers, one for each exhaust, as in the application of G. L. Reenstierna, filed March 21, 1900. I have shown in Fig. 2 of the accompanying drawings a mnfiier constructed substantially as shown and described in the said application, which comprises, essentially, two series of tubes or cylinders arranged concentrically,as at 19, 20, and 21 in Fig. 2. The respective cylinders of each series are perforated, as at 23 23,so that the exhaust upon being admitted to the innermost cylinder 19 escapes outwardly through cylinders The pipes engine-cylinders are conuntil it reaches the atmosphere. leading from the neet-ed,respectively,wi\h heads 25 25, applied l to the opposite ends of the muiiier, each head 25 having a central passage-way charges into the interior of the innermost cylinder 19 of the corresponding series. 'lhe proximate ends of the cylinders of the two series are closed by means of caps 31 and 32, fitted upon the cylinders 19 and 20, and a double cap or junction device, as 33, engaging with the proximate ends of the cylinders 21. The successive spaces between the cyl- 24, which disting'.

independent connections, whereby either one of said mufers may be employed according as heating is desired, substantially as dey scribed. n testimony whereof I ax my signature in presence of two Witnesses.
